    摘要: A steam generation apparatus is set forth including a housing; a boiler adapted to generate steam within the housing; a filler cap adapted to be removably coupled to the boiler; a first pressure relief device coupled to the boiler adapted to release steam at a first pressure level; and a second pressure relief device coupled to the boiler adapted to release the steam at a second pressure level, where the second pressure level is higher than the first pressure level, the first pressure relief device is incorporated into and is made to vent into the filler cap, and the second pressure relief device is made to vent internally to the housing.

    摘要: A steam power station, in particular a nuclear power station, includes a steam conduit leading through a wall and forming a fixed point with the wall for the introduction of forces and moments. A main valve is connected to the steam conduit at the fixed point, without a high-pressure pipe being interposed. Satellite valves, which have smaller nominal widths than the main valve, are fastened to the housing of the main valve, without a high-pressure pipe being interposed. At least one additional valve has a housing fastened to the housing of a satellite valve, without a high-pressure pipe being interposed and without any support.

    摘要: The invention relates to an emergency shut-off device, in the case of leakage, of a tube of a steam generator where the heat of vaporization is contributed by a liquid metal circulating in contact with the outer surface of the tube. The device includes on the terminal portion of the tube connected to the water supply device a tubular bush interposed in the path of the feed water. The bush contains a valve connected to the bush by a rupture part. The breakage of the part under the effect of an increased flow of water, in the case of a leakage, enables the closing of the outlet of the bush. The device includes also, in the terminal portion of the tube connected to the steam collector a bush containing a free valve enabling the steam outlet to be closed in the case of a leakage in the tube. The invention is applied in particular to steam generators of fast breeder nuclear reactors cooled by liquid sodium.

    摘要: An actuator head is provided for a pressure relief valve (1) having a valve element (11) spring biased to a closed position and arranged to be movable under the action of a fluid pressure medium in order to allow the escape of the fluid pressure medium through the valve for pressure relief purposes. The actuator head comprises an actuator (3) which is coupled with the valve element (11) and has a member (21) displaceable in response to fluid pressure applied thereto. A linkage (22, 19, 12) couples together the valve element (11) and the actuator (3) and has a lost-motion connection (72) which allows the valve element (11) to move against its spring biasing (13) for pressure relief purposes without imparting movement to the displaceable member (21) of the actuator (3). Biasing means (27) is arranged to oppose displacement of the displaceable member (21) of the actuator (3), and control means (4, 5) is provided to control the supply of fluid pressure to said displaceable member (21).The displaceable member (21) is arranged to be displaceable upon the application of fluid pressure to the member by said control means, so as to apply a supplementary valve-closing load to the valve element (11) via the linkage (22, 19, 12).In addition, a fail-safe mechanism is coupled with the linkage in such as way that the mechansim is movable with and forms part of the linkage during normal application of a supplementary loading by the actuator (3), but the mechanism is convertible, when the displaceable member (21) remains unintentionally in a displaced position under the action of fluid pressure and when the valve element (11) of the relief valve (1) carries out relief pressure movement, to a fail-safe mode in which the mechanism no longer forms part of the linkage (22, 19, 12) whereby no action is exerted between the actuator (3) and the valve element (11) via the linkage during the relief pressure movement of the valve element (11).

    摘要: A test circuit for use with a boiler control circuit. A test switch and a lamp are connected between ground and a water level electrode. In the presence of a water path, a sufficient potential drop exists between ground and the electrode to light the lamp when the test switch is closed. If a ground or short exists, the lamp will not light.
